Family members discovered Ja'Kye Joseph, 6, and his brother, Branario Minto, 5, submerged in the pool on the evening of May 22, BSO spokeswoman Veda Coleman-Wright said. The family members pulled the boys from the water, began CPR and called for help.

The boys were taken to Northwest Medical Center, where they were pronounced dead.

Investigators said surveillance video shows the boys unsupervised and running to the pool area at about 7:16 p.m. Detectives said the 911 call was received at 9:33 p.m. and the brothers had been submerged underwater for almost two hours before being found.

Detectives said Lynn failed to provide proper care and supervision for the brothers, which made him responsible for their deaths.

An additional arrest warrant has been obtained for the victims' mother, Wildline Joseph.
